This should all look nearly identical on the A460G waveguide shouldn't it?Burst decay spectogram (1/3 octave resolution ) of the DFM-2535 on an 520 mm diameter Ath Gen2 waveguide. For this, the frequency response was linearized between 1 kHz and 20 kHz.

34 drivers left: https://forms.gle/zszS5UC68y8xskvJ6
Follow up questions - will the drivers be shipped from the distributor directly to the buyers, or will you act as intermediary ?I assume the carrier will probably be DHL, and I do not know if there are special rates in place for businesses which we can benefit from. This said, the international shipping rate to the US available to private customers is currently 47.99 EUR. So probably in this ballpark region.
More information will be available when I transmit the list to the Tympahny distributor / dealer once the minimum order amount is reached. Possibly the week after next week.
I assume you are intermediary for the payments, is that correct? You will submit the complete payment to the distributor?
Do you know what the lead time is?
Do you know if the 47.99 EUR rate will cover the shipping for a single driver, or multiples?
Forgive me for asking so many questions upfront, I want to avoid unexpected costs later and have to pay much more than I wanted to, or cancel the order.
Thank you !
Yes.Follow up questions - will the drivers be shipped from the distributor directly
No, I hope not, otherwise my next tax declaration will be a PITA. It's an official dealer with good reputation. I strictly want to act as a broker for organizational purpose.I assume you are intermediary for the payments, is that correct?
I will receive more information next week.Do you know what the lead time is?
This rate is for a parcel of 5 kilo, 120 x 60 x 60 cm. Probably good for 5 drivers.Do you know if the 47.99 EUR rate will cover the shipping for a single driver, or multiples?
Most probably there will be some import duties.I want to avoid unexpected costs later
No, thanks for asking!Forgive me for asking so many questions upfront

Thanks for the detailed responses ! Please let me know when you hear about lead times and I'll decide then.Yes.

No, thanks for asking!
I expect there should be no customs duties for US customers if the order is below 800$ or so, atleast when ordering from TLHP I have not had to pay duties.
One more question in this regard: which throat adapter was used for the measurements? Maybe I've missed it, but whats the exit angle of the DFM-2535R00-08?This should all look nearly identical on the A460G waveguide shouldn't it?
Need to order some filament soon ;-)
Thanks, Daniel

This should be the STD-3 adapter https://www.diyaudio.com/community/...he-easy-way-ath4.338806/page-773#post-7765060 for the A520G2 https://www.diyaudio.com/community/...he-easy-way-ath4.338806/page-774#post-7766402, that matches the 21.7 degree exit angle https://www.diyaudio.com/community/...he-easy-way-ath4.338806/page-774#post-7766284 but does not utilize an insert that starts at the way to the phase plug. The difference to an unmatchd (degree?) adapter is not big, though. Some wiggles around 7-8 kHz are straigthened out, but a small step introduced at 5 kHz, when compared to the unmodified adapter: https://www.diyaudio.com/community/threads/acoustic-horn-design-the-easy-way-ath4.338806/page-767
Hehe, nice one. Sounds like you are the one who sound be asking 'are we nearly there yet?'traveling at the moment
Good news: we have reached our quota sometime last week and proceeded to the next phase: making the inquiry at Tymphany.
We are awaiting their reply by the end of the week and I will write with specifics then.
However, the whole procedure will likely take time, as Tymphany usually produces these batches on-demand. A possible exception is if there is still stock from a recent production run for an OEM left.

Re: this graph, was there any EQ boost below 1KHz? Or was this the natural response once it's in the A520G2 WG?
